To all whom it may conc rn: water from the condensed steam, an ordinaryBe it known that I, HEBER A. HOPKINS, a water-joint being thus formed,making the citizen of the United States, residing at West tanksteam-tight. Beneath the cover 16 is Roxbury, in the county of Suffolkand State an inner cover 18, having a central aperture of Massachusetts,haveinvented certain new provided with a vertical flange 19.

This can isprovided near its top In the accompanying drawings, Figure 1 is with ahorizontal flange 5, having a dependa plan view of my improved apparatusfor ing lip 6, which fits loosely over the vertical dispensing hotbeverages with the covers reflange 19 of the cover 18. *The bottom ofthe moved.

The casing A isprovided witha removable Steam-pressure within the tank 12 is pretopor-cover 16,-having a vertical flange on vented by means of a standingWaste-pipe d, its under side around the edge which pro .which alsoserves to take care of any overjects down into an annularV-shaped grooveflow in the event of the float-valve getting 17, formed around the upperedge ofthe casout of order.

' 0 ing A, said groove-being adapted to contain Gas is supplied to theburner 15 through a pipef, which enters the casing near its bottom andextends up within the tank 12 to the top of the water-supply pipe D,then over the same, and down to the burner 15. This gaspipe is providedat a suitable portion of its length with an automatic regulator E of anysuitable or well-known construction,by means of which the heat of thewaterin the tank is caused to control the supply of gas passing to theburner 15, whereby the water in the tank and the beverage in the can arealways automatically maintained at the desired temperature for use.

If desired, instead of a single beverage-can two or more may be arrangedwithin the casing, each provided with a separate draft-pipe and faucet.

The above-described apparatus is exceedingly simple in its constructionand combines many advantages not hitherto found in any apparatus of thisdescription with which I am acquainted.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In an apparatus for dispensing hot beverages, the combination of acasing having a removable coverand water-jointtherefcr,saidcasingforminga water tank'orbath and being provided with a faucet, abeverage-can arranged Within said tank or bath and connected with adraft-pipe extending through the casing and provided with a faucet ordraftcock, a supply-pipe for the water-tank having a float-valve withinsaid tank, a combustion-chamber beneath the water-tank, a gasburner insaid combustion-chamber and an automatic heat-regulating device for saidburner, adapted to be controlled by the temperature of the water in thetank.

2. In an apparatus for dispensing hot beverages, the combination of acasing having a removable cover and water-joint therefor, said casingforming a water tank or bath and being provided with a faucet, a wasteor outlet pipe for said tank, a beverage-can arranged within said tankor bath and connected with a draft-pipe extendingthrough the casing andprovided with a faucet or draft-cock, a supply-pipe for the water-tankhaving a floatvalve within said tank, a combustion-chamber beneath thewater-tank, a gasburner in said combustion-chamber and an automaticheat-regulating device for said burner adapted to be controlled by thetemperature of the water in the tank.

3. In an apparatus for dispensing hot beverages, the combination of acasing having a removable coverand water-joint therefor,said casingforming a water tank or bath and being provided with a faucet, abeverage-can arranged within said tank or bath and connected with adraft-pipe extending through the casing and provided with a faucet ordraft-cock, a supply-pipe for the water-tank having a float-valve withinsaid tank, a combustion-chamber beneath the water-tank, a gas-burner insaid combustion-chamber, an automatic heat-regulating device for saidburner, adapted to be controlled by the temperature of the waterin thetank, and a ventilating pipe or flue forsaid com bustion-chamber,whereby the fumes from the gas-burner are conducted outside the casing.

4:. An apparatus for dispensing hot beverages comprising acasing havinga removable cover and Water-joint therefor, said casing forming a watertank or bath and being provided with a faucet and a waste or outletpipe, a beverage-can arranged within said tank or bath and connectedwith a draft-pipe extending through the casing and provided with afaucet or draft-cock, a supply-pipe for thewater-tankhavingafloat-valvewithin said tank, a combustion-chamberbeneath the water-tank, a gas-burner in said combustionchamber, anautomatic heat-regulating device for said burner adapted to becontrolled by the temperature of the water in the tank, and aventilating pipe or fine for said combustion-chamhex-,whereby the fu mesfrom the gas-burner are conducted outside the casing.

5. An apparatus for dispensing hot beverages comprising a casing havinga removable cover and Water-joint therefor, said casing forming a watertank or bath and being provided with a faucet and a waste or outletpipe, a fixed cylindrical casing placed within the outer casing andconnected with a draftpipe extending through the outer casing andprovided outside the latter with a faucet or draft-cock, a removablebeveragecan fitting loosely within said fixed cylindrical casing andprovided at its bottom with a threaded nipple engaging a threadedpassage at the bottom of the fixed cylindrical casing in communicationwith the draft-pipe, a supply-pipe for the water-tank having afloat-valve within said tank, a combustion-chamber beneath theWater-tank, a gas-burner in said combustionchamber, an automaticheat-regulating device for said burner adapted to be controlled by thetemperature of the water in the tank, and a ventilating pipe or fine forsaid combustion-chamber, whereby the fumes from the gas-burner areconducted outside the casing.

Witness my hand this 14th day of October, A. D. 1903.
